Description
Technical field
The present invention relates to a kind of precision measurement apparatus, particularly relate to a kind of high definition image formula surveying instrument.
Background technology
Image measurer has another name called high definition image formula surveying instrument, which overcomes biography
system is thrownthe deficiency of shadow instrument is light, mechanical, electrical, the computing machine of collection
figurepicture technology in one
novelhigh precision, high-tech surveying instrument.The imaging of high magnification optical amplifier is carried out by optical microscope measuring targets, after the object image after amplification is sent into computing machine by CCD camera system, the profile of various complex part and the microcosmic detection of surface configuration size, angle and position, particularly precision parts and quality control can be detected efficiently.Can measurement data be directly inputted in AUTOCAD, become complete engineering
figure,
figureshape can generate DXF document, also can be input in WORD, EXCEL, carry out statistical study, can mark simple Xbar-S control
figure, obtain Ca, wait various parameter.
